' To all whom it may concern:

, through a container provided with a bottom and Fig.

Be it known that I, KMWVARuIN-o, a subject of the King of Denmark, residing at Copenhagen, Denmark, have invented cerma new and useful Improvements in Bot- V v VVhen some of the grate-bars are moved toms or Auxiliary Bottoms, for Use in Reservoirs, Silos, Reaction-Chambers for Sup'erphosphate, and the like, of which the following is a full, clear, and exact description. The invention relates to a bottom or auxiliary bottom for use in reservoirs, silos, and the like, which are to be emptied at foot in such a manner that the emptying can be controlled so as to take place successively.

Pulverent substances'such' as ground ce-- ment and the like possesses a-certain internal coherence, especially so the undermostparts which have been compressed through the weight of the material resting on the same, and such substances are sometimes packed so firmly that they will not fall down even if part of the bottom on which they have rested be removed, and it then becomes necessary to make the material fall down by blows on the container or by hacking down the material. Hereby it often occurs, however, that a considerable quantity of the material falls down at a tlme, and 1t 1s 1mpossible to cause the material to fall down in a regular controllable current.

The bottom forming the object of the present invention, consists of gratebars or girders, each or some of which are movable up and down in relation to the adjacent bars, and which when all of them in a certain position are at the same level, overlap each other with their edges so as to form a completely or almost completely closed bottom. 7

In the drawing annexed Figure 1 shows a vertical section througha number of special kind of grate bars forming'a bottom according to the present invention, Figs. 2-4 dia- Fig. 5,

grammatically other modifications. shows a somewhat diagrammatic section profiles are fastened, which serve for supporting roof-shaped plates a bent at an angle which 1s dependent on the angle of sliding of the substance-for whi'chjthe bot-torn isto and form an almost completely closed,'su rface;

out of level with the remainder of them openings will be formed between the bars ame of e1 m .iiratemaoa. 19, 19515; Application filed 3anua-ry12,"19'1. serial No. 811,?80.

bars and thus pass through the bottom. The

may be difi'erent according to the circumstances, the-nature of the material, etc. The

downward or the bars and :the bars 6" mav' all be moved away from the position ,m'anner in which the said bars are moved shown in full lines in order to give way for the passage of the material restingon the bottom.

The lists 9 shown-in Fig. 3 are fastened to the grate-bars e asshown in order to securetightness and th'us, prevent the 'unin tended passage of a finepulverule-nt sub stance. shown gutter shaped seals h on the plates'@ In Fig. 4 is for the same purpose for the same purposeand a bottom formed by such interlocking plates is under any circumstance powdrtight. 1 A bottom formed of. any of the shown forms of grate-bars may either be arranged horizontally or in some cases more or less obliouely.

'In Figs. 5 and dis illustrated by way of example a container m having an obliquely arranged bottom formedbv grate bars each second of which is movable up and down while the remainder are'fixed. One end of thegratebarse andf are suspended on a] fixed support Z formed by a rail or the like and the other ends ofthe bars ,7 are resting on a shaft 2' journaled at the lowermost edge of the container. whilethe endsof the bars@ tries 70 keyed onthe said shaft. When roare resting on the circumference of eccen- V tated'the eccentrics will cause the bars 6 to be alternately lifted to the position shown in Fig. 6. and lowered until contact with the bars fa'nd' at each revolution of the shaft 2' part of the material resting on the bottom will fall down between the grate-bars e and 7. By revolving the shaft i at d fferent speeds the passage of the material through the bottom may easily be controlled.

I claim V i 1. A bottom for emptying containers for comminuted materials comprising a plurality of substantially inverted V-shapcd bars adapted to support the said materials, means for moving certain of the said bars up and down, each second of the said bars overlapping the adjacent bars so as to form in a certain position a closed bottom. '2. A bottom for emptying containers for comminuted materials comprising a plurality of substantially inverted V-shaped bars adapted to support the said materials, means for moving certain of the said bars up and down, each second of the said bars overlapping the adjacent bars and closing means arranged on the latter adapted to coact With the said overlapping bars. I

In Witness whereof, I have subscribed my signature, in the presence of two Witnesses.
